A DYNAMIC ANALYSIS OF US EXPORT WHEAT PRICING AND MARKET SHARES AgEcon
Ahmadi-Esfahani, Fredoun Z.; Carter, Colin A..
The economics of a higher loan rate to support US wheat prices is analysed. Utilising optimal control theory, a dynamic wheat trade model is developed. The basic premise underlying the model is that the United States finds itself having transient monopoly power in the wheat market. An expression for the optimal pricing policy which maximises the present value of expected profits over the indefinite future is derived. Results from both the theoretical and empirical models demonstrate that the US wheat pricing strategy depends on its costs relative to competitors' costs, the discount rate and the competitors' response function. The main policy implication of the analysis is for the dominant wheat exporting country constantly to seek to lower costs relative...

A Note on Dumping, Interest Groups and the Public Policy Process AgEcon
Ahmadi-Esfahani, Fredoun Z.; Jensen, Paul H..
As a signatory of the General Agreement on Tariffs and Trade (GATT), Australia is permitted to impose duties on goods that have been imported below 'normal value' and have caused or threatened to cause 'material injury' to the domestic industry producing 'like goods'. There has been a recent push from various industries to increase protection for producers who have been injured by such practices. The Government is concerned, however, that harsher anti-dumping regulations will damage its position in the Uruguay Round of the GATT negotiations. As a result, a Senate Inquiry was established in 1990 to review Australia's anti-dumping legislation. The objective of this paper is to examine the effectiveness of the public policy process in addressing this issue....

A Simulation of the Grain Producers' Decision Problem at Harvest AgEcon
McClintock, David N.; Ahmadi-Esfahani, Fredoun Z.; Johnston, Jim H..
A simulation model is employed to find the least cost way of dealing with the grain carryover during and after completion of harvesting that is caused by a difference between harvesting and trucking capabilities in the short run. The study may potentially aid the farmer in the face of legislative changes affecting wheat marketing, as well as technological changes in harvesting equipment. Results tend to indicate that temporary paddock storage may be more efficient than contract trucking in managing the carryover.

Are Australian wholesale vegetable markets LOOPy? AgEcon
Nicols, Panos; Ahmadi-Esfahani, Fredoun Z..
Literature regarding the pricing efficiency of Australian wholesale vegetable markets is very limited. The objective of this paper is to test whether or not vegetable products traded in these markets are priced efficiently and satisfy the law of one price (LOOP). To that end, the price relationships between Adelaide and Melbourne markets are tested, using the Johansen cointegration approach, Granger causality and impulse response functions. The empirical findings do not appear to satisfy the LOOP. Policy implications of the analysis are explored.

Climate change and Australia’s comparative advantage in broadacre agriculture AgEcon
Sanderson, Todd; Ahmadi-Esfahani, Fredoun Z..
Australia has long been a major exporter of the products of broadacre agriculture, a production system well suited to the economic and climatic conditions of the country. According to the conventional wisdom, Australia holds a comparative advantage in these products, among which wheat and livestock products predominate. However, the future validity of this proposition is sensitive to the projected impacts of climate change. This paper develops a framework with which to quantify the future patterns of comparative advantage in broadacre agriculture given the projections of several global climate models. We find empirical support for the conventional wisdom, and note substantial resilience in Australia’s comparative advantage to adverse yield change.

Constant Market Shares Analysis: Uses, Limitations and Prospects AgEcon
Ahmadi-Esfahani, Fredoun Z.; Anderson, Glenn Michael.
Constant market shares (CMS) analysis compares the actual export growth performance of a country with the performance that would have been achieved if the country had maintained its exports relative to some standard. The approach was first applied to international trade in the 1950s and has generally been used to analyse trading patterns and, in particular, the extent to which poor export performance can be attributed to a loss of ‘competitiveness’. However, the approach has been open to objections as a tool of description and diagnosis. Recent revisions appear to meet objections concerning its role as a descriptive tool. However, CMS analysis remains open to objections as a diagnostic tool owing to the strict theoretical conditions required to yield an...

Constant market shares analysis: uses, limitations and prospects AgEcon
Ahmadi-Esfahani, Fredoun Z..
In this paper, we generalise the constant market shares (CMS) framework, with particular attention to the underlying theoretical conditions required for diagnostic interpretation. The approach is applied to the analysis of the export performance of the Australian processed food sector in South-East Asia over the period 1980–2003. We conclude that the usefulness of CMS analysis for evaluating a country’s international trade performance depends upon the empirical validity of the aggregation assumptions implicit in the diagnostic interpretation.

Corruption and economic growth in Lebanon AgEcon
Farida, Moe; Ahmadi-Esfahani, Fredoun Z..
This paper seeks to examine the impact of corruption on economic growth in Lebanon. Using a neoclassical model, we hypothesise that corruption reduces the country's standard of living as measured by real per capita GDP. We show that corruption deters growth indirectly through reducing the factor input productivity in a Cobb-Douglas production function. We provide empirical evidence suggesting that corruption increases inefficiencies in government expenditure and reduces investment and human capital productivity, leading to a negative impact on output. The implications of the analysis are explored.

Demand Under Product Differentiation: An Empirical Analysis of the US Wine Market AgEcon
Davis, Tim; Ahmadi-Esfahani, Fredoun Z.; Iranzo, Susana.
Oversupply has posed a number of problems for the Australian wine industry in recent times. When disaggregated from the industry level, however, the problem can be better described as a range of attribute-specific disequilibria. To date, solutions to this problem have predominantly revolved around reducing output through crop thinning or vine pulling. This paper proposes a different approach by suggesting that disequilibria may be reduced by gaining a better understanding of the demand for Australian wine. A discrete choice model of product differentiation is used to estimate the demand for wine in the United States, Australia's second largest export market. Implications of the analysis are explored.

Estimation of Factor Demand and Substitution in the Australian Pig Industry: A Dual Approach AgEcon
Buetre, Benjamin L.; Ahmadi-Esfahani, Fredoun Z..
This study seeks to estimate the rate by which inputs in Australian pig production are substituted for one another when prices change. It employs a dual approach to response analysis. Using cost shares of inputs and input price indexes for the period 1977-78 to 1990-91, a set of equations derived from a transcendental logarithmic function is estimated with symmetry and homogeneity constraints imposed. The results indicate that, with the exception of the demand for feed which is a vital production input, pig producers are very responsive to own price changes. The estimated elasticities generally differ in magnitude from similar studies of the Australian agricultural sector, and suggest that, at a lower level of aggregation, farmers are more flexible in...

Favoritism and allocative efficiency: a game theoretic approach AgEcon
Farida, Moe; Ahmadi-Esfahani, Fredoun Z..
This paper seeks to investigate the interaction between favoritism and allocative efficiency. The issue of whether corruption distorts allocative efficiency in a bribery game under a pre-existing environment of alleged favoritism is considered. It is demonstrated that if there is no unambiguous favoritism, observed favoritism in bribery game may disrupt allocative efficiency. A bribery game under corruption and favoritism is developed. The model and some possible equilibria are discussed. A simple numerical example from Lebanon is also presented.

GM technology and the Australian canola AgEcon
Taing, William; Ahmadi-Esfahani, Fredoun Z..
In this paper, we use a simulation model to measure the potential market and welfare effects of recently introduced genetically modified (GM) canola in Australia. The short-run results indicate that non-GM canola may emerge as a niche product commanding a premium. In the long run, GM technology appears to enhance aggregate welfare. However, when production cost savings are trivial and consumers become highly concerned about GM food products, aggregate welfare may decline. The policy implications of the analysis are explored.

How Has The Domestic Wheat Market Changed Since Deregulation? AgEcon
Wait, Marcus J.; Ahmadi-Esfahani, Fredoun Z..
This article evaluates the impact of deregulation on wheat growers. marketers and buyers. An analysis of market structure focuses on the market prior to deregulation, the stimulus for change and the ways in which parts of the wheat marketing chain have developed since deregulation. The change in AWB pool deductions for storage, handling and transportation charges, and the consequent change in seasonal marketing margins since deregulation are explored. The main finding of this preliminary study is that deregulation has been associated with reductions in freight and handling charges as well as seasonal marketing margins. Factors other than deregulation appear to have contributed to the reduction in the marketing margin and would bear further investigation.

Market power analysis in the retail food industry: a survey of methods AgEcon
Digal, Larry N.; Ahmadi-Esfahani, Fredoun Z..
The present paper surveys various methods used to analyse market power in the retail food industry. The strengths and weaknesses of these approaches are explored and a review of the issues in using New Empirical Industrial Organization (NEIO) and time-series models is provided. The absence of a theory underlying time-series models is highlighted and a review of some theoretical models in retailing is presented. The impact of imperfect competition in the food processing sector on retailing is also examined. It is argued that a combination of the approaches that minimises the weaknesses and builds on the strengths of single approaches may prove more promising for examining non-competitive behaviour.

Modelling Corruption in a Cobb-Douglas Production Function Framework AgEcon
Farida, Moe; Ahmadi-Esfahani, Fredoun Z..
In this paper, we extend the Solow growth model to include corruption as a determinant of the multifactor productivity using a Cobb-Douglas production function framework. In addition to the classical components of any growth model (output, labor, capital), we incorporate corruption as a determinant of government expenditure, investment and foreign aid. It is proposed that output and growth are influenced by the level of corruption. This model is to be tested empirically to trace the corruptive behaviour in Lebanon based on the available time series data.

Predicting performance in undergraduate agricultural economics AgEcon
Nolan, Elizabeth; Ahmadi-Esfahani, Fredoun Z..
Entry to the Bachelor of Agricultural Economics (BAgrEc) program at the University of Sydney is consistently less competitive than that for the Bachelor of Economics (BEc) and Bachelor of Commerce (BComm) programs. Given that students in the BAgrEc program undertake units in common with students in the BEc and BComm programs, it is of interest to examine the importance of school performance and first year university in the determination of success at university. This paper takes information for nine cohorts of BAgrEc students and tests their performance in first-year core subjects against the university entrance ranking, school English and mathematics marks, gender, and type of school. The paper then uses the same information to predict which student...

QUALITY PREMIUMS FOR AUSTRALIAN WHEAT IN THE GROWING ASIAN MARKETS AgEcon
Ahmadi-Esfahani, Fredoun Z.; Stanmore, Roland G..
An hedonic price function is applied to Australia's wheat exports to the growing Asian markets. The values for the quality characteristics in the wheat markets of Indonesia, Malaysia, Singapore, South Korea, and Thailand are estimated. The data base for the study is from the Australian Wheat Board shipments over the period 1984 to 1991. The sample is divided into two separate time periods to test the consistency in demand for export wheat and to trace recent trends in quality premiums. The implications of the results for wheat marketing and trade are explored.

Simulating economic values of a genetic improvement program for Australian farmed saltwater crocodiles AgEcon
Gray, Emily M.; Ahmadi-Esfahani, Fredoun Z.; Isberg, Sally R..
In genetic improvement programs, candidates for breeders are ranked by the profitability of their offspring, expressed as a weighted sum of the genetic gain from selection. In this paper, we estimate the economic values of a genetic improvement program for Australian farmed saltwater crocodiles. A bioeconomic profit function for a representative breeding pair is used to determine the optimal slaughter age following genetic improvement in each selection objective. The results indicate that estimated farm profitability increases by nearly # A111 for a 1-week reduction in juvenile slaughter age, # A78 for a 1 per cent increase in the proportion of first-grade skins produced, and # A33 for an increase in the number of viable hatchlings per clutch. The...

Structural Change in the Demand for Differentiated Meat Products in Sydney AgEcon
Gorny, Rachel A.; Ahmadi-Esfahani, Fredoun Z..
Concerns about the recent trends away from the consumption of red meat have led to tests for structural change in demand. These tests have typically treated the individual meats as homogeneous commodities. This article uses disaggregated data to test for structural change in the demand for differentiated meat products in Sydney over the seasons from winter 1987 to autumn 1991 using a revealed preference approach. The results fail to provide any evidence of structural change.
